This enables us to increase the flexibility and power of the modeling process in Simulink. - -For example, by using S-Functions, we can define all the steps that are performed during a typical Simulink simulation. For example, we can set the initial conditions, define how derivatives are computed, and directly define states and outputs as well as the dynamics of the system. -This can significantly speed-up the modeling process and lead to parametric, generic, clean and disciplined implementation of the Simulink simulation. - Also, if a model is complex with a large number of state-space variables, it is impractical to model every component as a basic Simulink block. Instead, we can write a model as a script and embed it inside of a Simulink block - There are Level-1 and Level-2 MATLAB S-Functions. - In this tutorial, we explain how to use Level-1 MATLAB S-functions. According to the information provided on the MATLAB website, it is suggested to use Level-2 S-functions. Level-2 S-functions are more capable. However, a large number of simulations are written by using Level-1 S-functions, and our experience shows that Level-1 S-functions are better documented with a large number of examples. - In future tutorials, we will explain Level-2 MATLAB S-Functions.
